 Drop the dollar sign from the awk print statement...

 awk -v C=$C '{print c}' coran.pls

 The dollar sign references the FIELD on the input.  So $c will display the
 c'th field of the line; a more familiar example is NF, or the number of
 fields.  By itself, NF, prints a number, but $NF prints the last field on
 the line.
